Phosphate-dependent behavior of the archaeon Halobacterium salinarum strain R1.
Article in Journal of bacteriology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Phosphate is essential for life on earth, since it is an integral part of important biomolecules. The mechanisms applied by bacteria and eukarya to combat phosphate limitation are fairly well understood. However, it is not known how archaea sense phosphate limitation or which genes are regulated upon limitation. We conducted a microarray analysis to explore the phosphate-dependent gene expression of Halobacterium salinarum strain R1. We identified a set of 17 genes whose transcript levels increased up to several hundredfold upon phosphate limitation. Analysis of deletion mutants showed that this set of genes, the PHO stimulon, is very likely independent of signaling via two-component systems. Our experiments further indicate that PHO stimulon induction might be dependent on the intracellular phosphate concentration, which turned out to be subject to substantial changes. Finally, the study revealed that H. salinarum exhibits a phosphate-directed chemotaxis, which is induced by phosphate starvation.
